Improved automatic press



UNITED STATES PATENT OFFICE.

IMPROVED AUTOMATIC PRESS.

Specification forming part of Letters Patent No. 49,877, dated September l2, 1865.

To all whom it may concern:

Be it known that I, PETERHAYDEN, ofPittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Automatic Press; and I do hereby declare that the followin g is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an elevation of my invention; Fig. 2, a vertical section of the same, taken in the line w w, Fig. l; Fig. 3, a plan or top view of the same; Fig. 4, a modification of a part pertaining to the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved press designed for striking up or swaging articles into various forms; and it consists in the employment or use of a feed-wheel in connection with a drivingwheel, a bolster-plate, a slide, and a cam, all arranged in such a man- 11er as to admit of the work being performed automatically and expeditiously.

A represents an upright framing, in which a slide, B, is fitted in grooves c a, so that it may work freely up and down g and C is what may be termed a driving-wheel7 having upon its axis D a cam, E, which in this instance is an eccentric, as shown clearly in Fig. 1. This cam E is tted and works in an elliptical opening, b, in the slide B, the major diameter of which opening is in a horizontal line. By means of this cam and elliptical opening it will be seen that a reciprocating motion will be imparted to the slide B on turning the wheel C.

In the upper part of the slide B there is an opening, c, through which a bolster-plate, F, attached horizontally to the framing A passes, the opening c being of sufficient dimensions as to admit of the proper movement of the slide B. On this bolster-plate F the feed-wheel G is placed, the latter being provided with teeth d, like those of aratchet, and having the pin H, on which it works, extending down through the bolster-plate F, with a spiral spring, e, upon it, said spring having a tendency to canse the headfof the pin to bear upon the feed-wheel and cause sufficient friction to prevent the casual turning of the latter.

rIhe feed-wheel G has a series of holes, g, made in it at equal distances apart, said holes being in a circle concentric with the wheel and extending entirely through the latter.

The slide B has two pins, I J, attached to it, one, I, depending from the upper edge of the opening c and the other, J, extending up vertically from the lower edge of said opening, the two pins being in the line with each other and with a hole in the bolster-plate F, in which the dies K are fitted. (See Fig. 3.)

The holes gin the feed-wheel are of such adiameter as to admit of the pin Ipassing through them.

The wheel C has a pin, L, projecting horizontally from it at such a point as to engage with the teeth of the feed-wheel and move the latter the distance of one tooth at every revolution of the wheel. By this means a hole, g, in the feed-wheel is brought in line with the hole in the bolster-plate in which the dies K are fitted.

The operation is as follows Motion is given the wheel C by any convenient power, and the articles to be swaged or struck up in proper form are placed in the holes g of the feed-wheel and brought consecutively over the dies in the bolster-plate, into which they drop, one at a time, and are compressed, swaged, or struck up in proper form by the descent of the pin I. The finished articles are forced up out of the dies into the holes g of the feed-wheel by the upward movement of the pin J, it being understood that the slide B descends and rises while the feed-wheel remains stationary, the pin L coming in contact with a tooth of the feed-wheel at the termination of each upward movement of the slide B. The nished articles are discharged from the holes in the feedwheel through a hole, h, in the bolster-plate.

I would remark that I do not confine myself to the use of the eccentric cam E, as a scroll or spiral cam, E', may be used, as shown in Fig. LI, said cam raising the slide and the latter falling by its own weight.

The device, it will be seen, works automatioally throughout and will perform its Work feed-Wheel and a pin attached to' O, or other rapidly. equivalent means, in connection With the bol- Having thus described my invention, I claim ster-plate'F and the pins I J, and operated from as new and desire to secure by Letters PatwheelGthrough the medium ofa cam, substanentm ''t'afllyas and for the purpose herein set forth.
